Testing in Production (TiP) really happens, and yes that it s a good thing! Here are some examples from Facebook, Amazon, Google, and Microsoft. The Methodologies This is not a complete list of TiP methodologies, but explains the ones used in the examples given A/B Testing (aka Online Controlled Experimentation): I explain this in…

Let’s start with some definitions: Death Demise, end, termination, the state of no longer existing BUFT “Big Up-Front Testing” an activity or “Big Up-Front Test” a group that carries out that activity (the latter sounds cool, like “Big Pharma”) It’s an acronym of my own invention. At least I believe this to be the case…

[Going to try a mini-post…keeping it short and focused] In my previous post I introduced you to Online Experimentation. The general use case for experimentation is to take two or more websites or services, each with different features or designs, and test them against each other using real users. It is assumed that all the…

One topic I hope to return to many times in this blog is that of TiP, or Testing in Production. For a good introduction to this check out Ken Johnston’s blog entry TIP-ING SERVICES TESTING BLOG #1: THE EXECUTIVE SUMMARY which is an updated version of the executive summary of the ThinkWeek paper that I…
